Space biosignatures demand patience: confirmations of life clues take years
TL;DR
Astronomers detect molecules in space by matching spectral fingerprints from radio and infrared telescopes; while hundreds of astrochemical detections exist, claims of life-related molecules (like glycine in space or phosphine on Venus) have often been revised upon further scrutiny, illustrating that confirming potential biosignatures on distant worlds requires multiple signals, replication by independent teams, and time—so excitement about life’s clues tends to fade into cautious verification.
